Molecular Oncology, Volume 19, Issue 4, Page 1203-1228, April 2025.MiR‐99a‐5p/miR‐100‐5p (functionally identical) and miR‐125b‐5p microRNAs are downregulated in malignant germ cell tumors (GCTs). Combination replenishment of these microRNAs using mimics resulted in growth inhibition in representative cell lines, with consequent downregulation of target genes involved in cell cycle (confirmed by flow cytometry) and ...

Information Measures for Microphone Arrays [PDF]
arXiv, 2018 We propose a novel information-theoretic approach for evaluating microphone arrays that relies on the array physics and geometry rather than the underlying beamforming algorithm. The analogy between Multiple-Input-Multiple-Output (MIMO) wireless communication channel and the acoustic channel of microphone arrays is exploited to define information ...

Configurable 3D-integrated focal-plane sensor-processor array architecture [PDF]
, 2008 A mixed-signal Cellular Visual Microprocessor architecture with digital processors is described. An ASIC implementation is also demonstrated. The architecture is composed of a regular sensor readout circuit array, prepared for 3D face-to-face type ...

Molecular Oncology, Volume 19, Issue 4, Page 1132-1154, April 2025.PIK3CA amplification and PIK3CA mutation enhance ovarian tumorigenicity through an activation of AKT, which phosphorylates YAP at Ser127. This Ser127 phosphorylation leads to the retention of YAP in the cytoplasm and triggers RAC1 activity, promoting cell migration. Additionally, AKT activation increases expression of N‐cadherin, which further enhances

Analysis of Multi-Antenna GNSS Receiver Performance under Jamming Attacks
Sensors, 2016 Although antenna array-based Global Navigation Satellite System (GNSS) receivers can be used to mitigate both narrowband and wideband electronic interference sources, measurement distortions induced by array processing methods are not suitable for high ...

Serpentine array processing [PDF]
The Journal of the Acoustical Society of America, 1993 Often one must determine the wave-number spectra of complicated spatial wave fields, which contain significant energy propagating in a broad range of directions. In this case a single linear array must be steered to endfire to compute some of the wave numbers of interest.

Molecular Oncology, EarlyView.This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

A Multi-Antenna Scheme for Early Detection and Mitigation of Intermediate GNSS Spoofing
Sensors, 2019 This article presents a method for detecting and mitigating intermediate GNSS spoofing. In this type of attack, at its early stage, a spoofer transmits counterfeit signals which have slight time offsets compared to true signals arriving from satellites ...

Acousto-optic signal processors for transmission and reception of phased-array antenna signals [PDF]
, 1991 Novel acousto-optic processors for control and signal processing in phased-array antennas are presented. These processors can operate in both the antenna transmit and receive modes.

Molecular Oncology, Volume 19, Issue 4, Page 1117-1131, April 2025.This study shows that patients with gastrointestinal adenocarcinomas can be stratified into six distinct subtypes based on genome‐scale DNA methylation profiling. This stratification, achieved using a robust analytical framework, aligns with established tumor characteristics and holds potential to support prognostication.
